| DateTimeScaleOptions |

Remarks
Use the Holidays property, to manually populate the collection of holidays.
Alternatively, you can import holidays in the DevExpress Scheduler (.xml) or Microsoft Office Outlook® (.hol) formats from a file, via the WorkdaysOptions.LoadHolidays method.
Note
If a date is defined as both a holiday (via the Holidays property) and strict workday (via the WorkdaysOptions.ExactWorkdays property), it is considered working day, and, consequently, it is not excluded from the axis scale.
For more information, refer to Data Aggregation.
Example
This example demonstates how to exclude non-working days (weekdays and holidays) from an axis range, via the AxisBase.WorkdaysOnly and AxisBase.WorkdaysOptions properties.
